Hello
I've been lurking in the forums for a while in order to figure out if Freenas is right for me.
I originally thought that Unraid would suit my needs better, but examining the different workings of Unraid vs Freenas I'm not so sure anymore
I think I've gotten most of my questions answered but there are some things I'm still a bit unsure about:
Reading Cyberjocks slideshow here made me understand the following:
- Once I create a vdev with any number of disks I *cannot* add disks to that vdev at a later time.
So, this means if I want ot maximize the available space in a pool, I should just fill my controller to capacity (In the case of M1o15 that would be 8 disks) add all 8 disks to 1 vdev and set it for RAIDZ2 or RAIDZ3 depending on how low I want the risk of a complete vdev failure.
I currently have 3 x 4TB WD RED with 1 disk for parity.
Another way of doing the above could be to buy 1 extra disk now, create 1 RAIDZ2 with the 4 disks. add it to a pool and perhaps at a later time add 4 more disks in a RAIDz2 vdev
I've also seen that you can have alot of 2 disk mirrored vdevs in 1 pool.
Technically this would protect me from 1 disk failure in each vdev, the rebuild time should be faster, but it just seems that a 4 disk RAIDZ2 vdev is better protected.
However, 2 disk vdevs seem more flexible when it comes to incrementally upgrading your storage capacity.
My question is: What is the best scenario for home use? 2 RAIDZ2 vdevs with 4 disks in each or 4 mirrored vdevs with 2 disks in each?
Also, what do you guys use for backups? I've been looking at an online solution like crashplan
